Genlock issue on ikegami HC-230

Hello, I run a show on my college TV Network, we recently just purchased an ikegami HC-230 to use as an additional camera in the studio. We also have an Ikegami HC-240 with an MA-230/a camera control unit. According to Ikegami's website the MA-230 ccu should be compatible with the HC-230. When we tested the HC-230 and had it connected to the HC-240's ccu (the MA-230/a) we couldn't get a clear picture. When the HC-230 is not connected to the ccu and is powered via the ac power adapter it works fine, and we get a clear picture. I think it might be an issue with the gen lock but I'm not entirely sure. Any help would be appreciated.
